2 Claims. (Cl. 128-290) This invention relates to improvements insanitary napkins.

The principal object of this invention is to provide a sanitary napkinwith a deodorant enclosed therein.

A further object is to provide a sanitary napkin wherein the deodorantis contained in a separate package and exposed to the atmosphere onlywhen the napkin is being used.

A further object is to provide a means for dispensing of the deodorant,which may take the form of a sachet or of other volatile substanceswithout the possibility of the deodorant coming in contact with the bodyof the user so as to cause irritation to the skin, as some persons areallergic to the essential oils.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings forming a part of this specification and inwhich like numbers are employed to designate like parts throughout thesame,

Fig. 1 is a fragmentary end view of a sanitary napkin in extendedposition and having my invention applied thereto;

Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a similar cross-sectional view showing the attaching tab ofthe napkin in folded position; and

Fig. 4 is a similar view showing a separable capsule containing thedeodorant.

An ordinary sanitary napkin is usually made of a pad of absorbentmaterial enclosed in a gauze wrapping. The ends of the wrapping are usedto attach the napkin to suitable supporting means worn by the user.

In packing these napkins they are folded so that the end tabs lieparallel to the body of the pad. This wrapping material is somewhatstretchable.

In using my invention, I depend upon the unfolding and stretching of thematerial to separate portions of the deodorant container.

In the accompanying drawings, wherein for the purpose of illustration isshown a preferred embodiment of my invention, the numeral 5 designatesthe pad as a whole, which consists of an absorbent material 6 having acovering 7 which covering extends beyond the end of the pad so as toform a tab 8, which tab is used to secure the pad to a garment of theuser.

My invention consists in inserting an envelope-like con- 2,940,449Patented June 14, 1960 tainer 9 adjacent the end of the pad and withinthe gauze wrapping or covering 7.

This envelope-like container is secured to the gauze at the point Aeither by stitching or through the use of an adhesive. The opposite endof the container is secured to the gauze at the point B either bystitching or through the use of an adhesive.

The result of this construction is that when the tab 8 is unfolded fromthe position shown in Fig. 3 and stretched to the position shown inFigs. 1 and 2, the envelope-like container will be torn so that thesachet or other deodorant contained in said impervious envelope will bereleased. The body warmth of the user will cause the essential oilstherein to become volatilized thus completely hiding any otherwiseobjectionable odors which might emanate from the pad.

In the modified form shown in Fig. 4 I have employed a separable capsulemade of parts C and D which are adhered to the gauze in such a mannerthat when the same is stretched, the two parts of the capsule will bepulled apart, thus releasing the contents of the capsule, which contentsconsist of deodorant substances.

It will thus be seen that I have constructed a sanitary napkin whichwill accomplish all of the objects above set forth.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same and thatvarious changes relative to the material, size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In combination with a sanitary napkin having a pad and a gauze covertherefor, of a receptacle positioned in said napkin at a point betweensaid pad and said gauze covering and adjacent the end of said pad, saidreceptacle being separable, so that the contents thereof will bereleased when said parts are separated, and means for adhering theopposite ends of said receptacle to said gauze, whereby the stretchingof said gauze will cause said separation.

2. In combination with a sanitary napkin having a pad and a gauze covertherefor, of a receptacle positioned on said gauze, one end of saidreceptacle being secured to said gauze at a point adjacent said pad, theopposite end of said receptacle being secured to said gauze at a pointgreater than the length of said receptacle, thereby creating excess'gauze material between the ends of said receptacle whereby when saidgauze is stretched to its full length said receptacle will be stretchedand ruptured to release its contents.
